Application filed August 3, 1925. ser al No. 4?,741.

The present invention relates to improve ments in door hinges, and it isthe principal object of the invention to provide a hinge consisting of aplurality of leaves allowing a convenient raising of the door withoutthe necessity of removing the pintles which frequently rust in and arehard to remove.

Another object of the invention is the provision of a door hingeequipped with means for holding the door open, if this is desired.

A further object of provision of a multiple-leaf door hinge of simpleand inexpensive construction which may be easily fastened to any door,and is 5 especially well adapted to be applied to adjacent doors inwhich case one hinge is sufli cient for both doors.

A still further object of the invention is the provision of a multi-leafhinge, the pintle of which is spring-controlled for normal lyholding'the door lowered, but allowing a ready raising of the same ifsuch is desired for instance when laying carpets or the like.

These and further advantages of my in known as the vention will becomemore fully description thereof proceeds and will then be specificallydefined in the appended claims.

In the accompanying drawing, forming a material part of this disclosure:

Fig. 1 is a front elevation of two adjoining doors equipped with a pairof hinges constructed according to the present invention.

Fig. 2 is an enlarged detail front elevainvention.

Fig. 3 is a cross-section on line 33 of Figure 2. The hinge comprises acentral leaf 10 provided with a plurality of openings 11 bevelled, as itis-customary for the reception of the fastening screws 13 or the like.

The leaf 10 has two lateral wings or pintle sockets 13 and 14 for thepassage of the pin- 7 tles 15 and 16 which also pass through the pintlesockets 17 and 18 at the lower ends of the inner faces of the lateralleaves 19 and 20 respectively sockets 21, 22, at the the leaves 19 and20. have the customary upper heads 23 and 2 1, and screw holes 25 and26. The inner lateral edges of the leaves 19 and 20 are cut away so asto form spaces 27 and 28 with the outer cut-away edges of the centralleaf 10.

In these spaces spiral springs29 and 30 are wound about the pintles 15and 16 restupper inner edges of the invention is, thetion of amulti-leaf hinge according to the and through similar, but smaller Thepintles 15 and 16 7 ing with their lower ends upon collars 3i and'32 onthe pintles which eachcarry a pin 33, and the upper ends of the springs29 and 80 are hooked into perforations of eyes formed with the outercentral leaf edges, as at 34 and 3,5.

The central leaf 10 carries on its upper part a knob 36 adapted tooperate a latch 37 having its upper .end recessed as at 37 and 38adapted to engage the pins 33 respectively on collars 31 and 32. Theknob 36 is suitably spaced from thecentral leaf by a collar 89, and theconstruction of knob and its spindle is such that the latch 37 in itsposition of rest will be frictionally held in its upright position shownin Figure 2 but allow'a ready swinging of the latch into its pinengaging positions. e

-The operation of the device will be entire- 1y clear from the abovedescription, if it is desired to raise a door, 't is simply necessary tolift the door in order to allow for instance the convenient laying of acarpet 40 and to lockthe door by the proper operation of the 30 latch.NVhen the work is done the door is allowedto slide down again and toform a tight seat on the carpet. If it is desired to keep a doortemporarily open, the latch is engaged with pins 33 in the mannerindicated in Figure 3. The springs will allow a convenient raising ofthe door for which the hinge leaves are suitably spaced to allow theproper motions, and the springs, will thenhold' the door again tightlyclosed.

It is to'be understood that while I have described and shown one form ofmy invention as an example, the hinge may be executed in many other waysand changes may be made in the construction of its minor details such asfall within the scope of the appended claims, without departure'from thespirit of my invention. 7

Having thus described my invention, what I claim as new and desire toprotect by Letters Patent is as follows:

'1. Hinge comprising a central leaf member and lateral, auxiliary leafmembers, integral pintles secured at upper and lower ends to one of saidleaf members for hinged- 1y securing the lateral leaves to said centralleaf at opposite edges thereof, springs wound about one part of saidpintles and secured with their upper ends to said central member,collars on said pintles on which the lower ends of said springs rest,pins on said collars, and a latch movably secured to said central memberand spaced therefrom at the inner upper and lower edges of said lateralwings, integral pintles passed through said sockets having upper heads,said pmtles being secured to one of said leaves to prevent movement ofthe latter relative to said pintlc, collars on said pintles within theupperspace between the central and lateral hinge members, pins on saidcollars, springs wound about said pintles within the said spaces,resting with their lower ends upon said collars, eyes formed on theouter upper edges oisaid central member to which the upper ends of saidsprings are secured, a latch, a knob for turning said latch about itsspindle, means for spacing said latch from the central hinge member, andan upper head on said latch recessed on both sides for allowinganengagement of said recesses by said pins to lock the doors to which saidhinges are secured in their open and raised position, and means-forsecuring; said hinge members to a door and to two adjacent doors having;a common jamb.

In testimony whereof I have affixed my signature.
